With this specific reproduction code I'm not sure if we want to change this. If you specifically override the relationship name with a custom value, I think that should be respected? I'd expect Laravel to behave the same way if you added a foo.bar column, it'd be reasonable for $foo->bar to return foo.bar rather than using a relation.
